Centrifugal pumps are some of the most commonly used for handling corrosive or hazardous substances.
These pumps transport liquids safely and securely from one place to another. They operate using centrifugal force, drawing liquids into the pump through a rotating impeller and creating pressure differences that force them out through an outlet.
The science behind how these pumps work allows for efficient and effective liquid transfer for various applications across multiple industries.
Due to the nature of what these pumps commonly transport, training, maintenance, and proper use are essential for protecting the three most important E’s of manufacturing: employees, equipment, and the environment.
Below are the top five tips for centrifugal pump safety in the workplace:
- Manufacturer’s Instructions
When in doubt, follow the manufacturer’s instructions.
These instructions typically cover pre-use inspections, installation, operation, maintenance, and shutdown procedures.
Specific instructions will emphasize proper installation, and clearance checks, and include details on electrical connections and other safety precautions.
- Regular Inspections
Regularly inspect and maintain your centrifugal pumps, this will help ensure they continue operating safely in your sustainable manufacturing plant.
The best method for ensuring these crucial inspections take place is to schedule them with your maintenance teams on the floor.
Scheduled inspection programs are successful because they assess components prone to wear and tear or damage, such as seals and bearings.
- Proper Installation
Before installing your new API 610 Pump, you must find a suitable location.
When searching for the perfect place, some essential things to keep in mind are ground stability and power proximity.
Lay a level foundation to support the pump, knowing that it will vibrate with use. These pumps can be coupled to a motor – if you are doing that, make sure the coupling is installed correctly and the pump can be easily accessed by maintenance teams.
- Employee Training
The number one tip for training your employees on how to use a centrifugal pump safely is to first ensure that every one of them understands the basic principles.
Focus on key areas like hands-on experience, performance curve reviews, vibration analysis, and basic maintenance to start. That will give your employees a comprehensive understanding of these impressive pumps and improve their ability to operate them safely.
- Start-Up and Shutdown Procedures
During the start-up, prime the pump by filling its suction line with liquid by opening a vent or filling plug to release any trapped air.
Never operate a pump without liquid in it.
Open the suction valve to allow liquid to flow into the pump, close the discharge valve at first (or open it slightly, depending on the conditions), and start the motor. Rotating the impeller will generate suction and the pump will start working.
Once the pump is working, slowly open the discharge valve to enable the liquid to flow into the system.
When shutting down, close the discharge valve slowly and, if needed, follow a systematic depressurization process. Do not leave the pump running with no liquid flow – that will damage it.
